The current in the circuit is increased, the resistance of the electromagnetic resistance block 10 is increased, the current is reduced, the resistance is reduced, and therefore the opening and closing speed of the safety door can be stabilized.
See fig. 6, 9; when the evacuation of passengers is finished, the accident is solved, and the safe escape door needs to be closed. At this time, in the motor driving module 25, the connection between the pawl 27 and the descending ratchet wheel 12 is disconnected through a clutch structure, the engagement connection between the ascending ratchet wheel 11 and the pawl 27 is replaced, at this time, the motor rotates in the reverse direction, the hinge transmission device 4 is driven to rotate, and the safety door slowly ascends.
In the air pump control module 19, the switch of the three-position four-way electromagnetic directional valve 34 is switched to switch on the right side, air pressure is output from the air pump 32, and the air pressure passes through the three-position four-way electromagnetic directional valve 34, the pneumatic one-way valve 37 and the safety door pneumatic telescopic rod 38, so that the safety door pneumatic telescopic rod 38 slowly contracts, and the safety door body 1 gradually rises. When the output air pressure is too large, the air is discharged through the overflow valve 33, and the air flow is controlled to be stable. When the safety door is completely closed, the door frame seam allowance 5 returns to the designated position, the speed sensor 17 and the smoke sensor 18 detect the door frame seam allowance, the electronic control unit 21 carries out decision processing on signals, if all the signals are normal, the vehicle double-flash alarm lamp 13, the alarm horn 14, the air pump control module 19, the safety door opening alarm 23, the electromagnetic resistance module 24, the motor driving module 25 and the emergency signal lamp control module 26 are closed, and if the door needs to be stopped at any time in the opening or closing process, the emergency stop button 22 is pressed to realize the function. Then the seat in the passenger car can be selectively moved or not according to the desire of the passenger.
